Television works just like the theory of evolution: only the strongest survive. You pull in strong ratings, you keep getting renewed, regardless of your content. Sometimes a critically acclaimed award-winning series with low ratings will squeak by, but those are rare.

Upfront announcements are coming up in May, so we thought we'd provide you all with a list of network and cable shows and the status of their renewal chances: safe, in danger, already renewed, already canceled or on the dreaded bubble. This will give you enough time to prepare to mourn a series or celebrate another season…
